IPC: G02F1/09
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of pits in an LEP(liquid phase-epitaxial) film used as a magnetooptical element material even at the time of growing the LEP film having an increased thickness and also, to inhibit the loss in mass of a platinum crucible from being caused in the growth process of the LEP film, in the production. SOLUTION: In this production, a melt in a platinum crucible in which a magnetic garnet single crystal raw material is melted, is maintained at a growth temp. such that the melt is in a supersaturated state and in that state, a nonmagnetic garnet substrate used as a seed is immersed in the surface of the melt to grow a single crystal film on the surface of the substrate by a liquid phase-epitaxial(LEP) growth method and to produce a magnetooptical element material. At this time, a high temp. maintenance stage for maintaining the melt at a higher temp.  (e.g. >=950 deg.C) than the growth temp. and a growth stage for growing the single crystal film at the growth temp. are altemately and plural times repeatedly performed, wherein: the first high temp. maintenance stage is a stage for melting and agitating the raw material and maintaining the resulting melt in the above high temp. state;  and each of the second and the following high temp. maintenance stages consists of three steps, i.e., a step for gradually cooling the substrate on which the single crystal film is formed, by utilizing a temp. gradient within a furnace and thereafter taking out the substrate from the furnace to its outside, a step for replenishing the melt in the platinum crucible with the crystal component (i.e. the raw material) in an amount equivalent to the amount of that consumed by the growth of the single crystal film and a step for maintaining the melt in the above high temp. state and agitating the melt.

Title: Liquid crystal display element
Inventor: OKADA SHINJIRO
IPC: G02F1/133
Filed: 1993-12-14
Abstract: PURPOSE:To obtain the liquid crystal display element which makes a gradational display with superior reproducibility by suppressing the movement of a domain wall by improving its driving method. CONSTITUTION:When gradational information is displayed by selecting and writing the same pixel in the same frame, a plus and a minus bipolar pulse of the same type are used for at least 2nd and succeeding write waveforms. Namely, when one pixel on one scanning line is written plural times, a voltage pulse which is of the same type with a 1st write pulse, but opposite in polarity is applied precedently for 2nd and succeeding writing operation and then a write pulse is applied to write the pixel. For example, a compensating pulse 2' is applied. Once the compensating pulse 2' is applied, the domain wall moves like it expands momentarily or stably to the point of a white domain C'' as shown by an arrow. This movement causes no substantial unnecessary increase of a black domain (unnecessary decrease of a white domain) even when a next pulse is applied.
